The usual method is to bisect your setup-orgmode.el file: comment out
the bottom half and if that makes it work, then you know that the
problem is in the part that you commented out. Recursively, bisect
further.
I downloaded your setup-org.el and tried it out. There are two things
that I commend out: the (use-package org-bullets ...) stuff - the
`emacs -Q -l setup-orgmode.el' complained about use-package and I was
too lazy to add whatever is necessary to get it and the (add-hook
'org-mode-hook wrap-region-mode) stuff because I don't have
wrap-region-mode installed. With those two deletions, I see no
problem. I doubt that the problem is with org-bullets, so try getting
rid of wrap-region-mode and see if that does the trick. Of course, it
may be that there is some interaction between your Org mode setup and
all the *other* setup that you do, but bisecting is still the way to
go.
